This invention relates to radiator fronts particularly those havingshutters therein which may be controlled from the automobile seat. Theinveiitio'n is fully described in the following specific-ation and showniii in the accompanying drawings, in which- `Figure 1 is a Verticalsection through an automobile radiator sliowing a front embodying theinvention,

Fig. 2 is a liorizontal section through the same on the line 2-2 of Fig. 1,

Fig. 3 is a side elevation of the radiator and front showing the controltlierefor,

F ifl'. 4 is an enlarged partial section on the line 4-4 of Fig. 3,

F ig. 5 is a Vertical section through the front on' the line 5 of Fig.2,

Fig. G'is a rear view of' the same,

Fig. 7 is a front view 'of the radiator front, and

F igs. 8 and 9 are enlarged' prospective views of the ends of thesliutters.

The embodiment illustrated comprises a radiator of awell-known typehaving upper and lower reservoirs 10 and 11 respectively connected bymeans of Vertical tubes 12 and having a series of horizontal fins 13.

My radiator front which is adapted to be secured to this radiator has aframe coinprising a web 14 and a flange 15, the latter being bolted tothe front of the radiator by means of bolts 16 which pass throughopenings 17 in the radiator front and through the spaces between thefins 13. and the pipes 12.. V

Across the middle of the radiator front is disposed a series of sliutterblades or vanes 18, 19 and 20, as shown in Fig. Each vane has a centraldisposed pin 21 at one Vend and a crank 22 at the other, these piiis andcranks being journalled in Vertical side members 23 which are carried bythe members 14. o The vanes 18. are preferably formed from sheet metaland are secured to the flattened ends of the pins 21 and cranks 22 as byspot Welding. The meeting edges of the ad]a cent vanes overlap as isshown in Fig. 5, these edges being preferably curved -as there shown forthis purpose.

The cranks 22 of the upper set of vanes 18 are all of the same lengthand are set at the same angle with respect to the vanes 18, the crankarms of each of these cranks passing through a movable member 24 whichis normally pulled upward into closed position as shown in F igs. 5 and6 by means of a tension spring 25, the vanes serving as `stops for eachother when. closed.

-mounted and a pin' 29 as shown in Fig. 4.

A spring 30 forces this lever toward the plate 31 to which it ismounted, this plate being secured to the steering coluinu v32 by meansof a band 33 and a bolt 34. This plate has a series of holes 35 thereiiiwhich are adapted to be entered by the tongue 36 which is carried bythelever 28.

As the operator draws the lever 28 back it. acts through the Wire 27 andthe operating lever 20 to rotate the upper vane about its piv'ots and'at the same tiine the movable men'ibei- 2-l which coimects all of thecranks 22 of the upper set of vanes 18, causes all of lthese vanes tosimultaneously turn' toward opening position. The several open- -ings35v iii the plate 31 correspond to'varying ilegress of opening oftheseupper vanes.

The next set of vanes 19 are similarly mounted, the cranks 22 however,being shorter than the cranks 22 of the upper set of vanes 18. Thecranks, 22a likewise are all set at the same angle and are connected toa single movable member 24* which is in line with the movable meiiiber24 and separated therefrom by sucli an interval that as the, member 24is moved down with the opening of t'he vupper set of vanes 18, it will'contact the meinber 24a only after the vanes 18 have been moved throughan angle of about' 30. Any further lopening movement therefore of thevanes 18 Will cause the member 24 to depress the member 24a therebycausing the vanes 19 of the central group lto open simultaneously with afurther opening ofthe upperwanes 18.

Similarly the vanes 20 of the lower group have cranks 22b which areshorter still than the cranks 22ai 'The cranks 22b are all connected bymeans of the inovable member 241' which lies below the member 24a and isSeparated therefrom by the interval so that as the member 24a movesdowmvardly during the opening of the vanes 18 and 19, it

will strike the member 24h at a predetermincd point, after which allfree members 24, 242* and 24h will move down together. Owing however tothe fact that the cranks 22a are shorter than the cranks the vanes 19will be given a greater angular movement for a given movement of themembers 24 and 24:a and likewise since the cranlrs 22h are shorter thanthe cranks 22a, the vanes 20 will be opened even more rapidly. Theseparts are so proportioned that when the operating lever 26 has beenmoved to its full opening position which is substantially 90 from theposition shown in full lines in Fig. 5 and when the tongue 36 willengage the last hole in the plate 31, all three sets of vanes 18, 19 and20 will be substantially full opened.

Thus it will be seen that the vupper set of vanes 18 will be opened'first while the vanes 19 and 20 remain closed thereby permitting theupper portion of the radiator to be cooledI by air passing through theopen upper set of vanes. By a further movement of the lever 28 the upperset of vanes 18 is opened still further while the middle group 19 ispartially opened. By further movement of this lever the lower group ofvanes 20 is also opened 'lwhile those above are opened still further'and a still further movement of this lever opens all groups to the fullopened position.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable'of many modiications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims.

I claim:

1. In a radiator front, a series of vanes movable to substantially openor close said front to the passage ofair, said vanes being divided intogroups, each vane having an operating` crank connected thereto, thecranks of each group -being of the same length, and. set at the sameangle, a member operably connecting said cranks of each group, a springtending to return each group of vanes to its closed position, saidmembers being Separated by intervals and adapted to operatively cngagethe succeeding members, so that the members of the iirst group whenoperated to open ters engage the members of the next group, forcing themto open as the first group continues to open, and so on with the nextgroup until all groups are open.

2. In a radiator front, a series of vanes movable to substantially openor close said front to the passage of air, said vanes being divided intogroups, each vane having an Operating crank connected thereto, thecranks of each group being Iof the same length, and set at the sameangle, a member operably connecting said cranks of each group, a springtending to return' each group of vanes to its closed position, saidmembers being Separated by intervals and adapted to operatively engagethe succeeding members, so that the members of the first group whenoperated to open the shutters engage the members of the next group,forcing them to open as the first group continues to open, and so onwith the next group until all groups are open, the length of the cranksof each group successively decreasing.
